一、技术选型
还有一个更好的google FS（但是他不开源，我也没找到社区版一类的可以不要钱使用的）。
最后考虑到我们存储的都是10M以下的图片，而且访问量不是很高，所以使用了国产的fastDFS(当然也包含爱国情怀)。
二、fastDFS组成部分
Tracker Server： 主要负责调度工作，起到均衡的作用，管理所有的 Storage Server 和 Group。每个 Storage Server 在启动后会连接 Tracker，告知自己所属 Group 等信息，并保持周期性心跳。多个 Tracker 之间是对等关系，不存在单点故障。Tracker Server 在内存中记录分组和 Storage Server 的状态等信息，不记录文件索引信息，占用的内存量很少。Tracker Server 作为中心结点，管理集群拓扑结构，其主要作用是负载均衡和调度。
Storage Server： 主要提供容量和备份服务，以 Group 为单位，每个 Group 内可以有多台 Storage Server。组内的所有 Storage Server 之间是平等关系，会相互连接进行文件同步，从而保证组内的所有 Storage Server 的文件内容一致。Storage Server 直接利用 OS 的文件系统存储文件，不会对文件进行分块存储，客户端上传的文件和 Storage Server 上的文件一一对应（V3 引入的小文件合并存储除外）。每个 Storage Server 的存储依赖于本地文件系统，可配置多个数据存储目录。
Client： 与 Tracker Server 和 Storage Server 交互，负责文件的上传、下载、删除等操作。客户端可以指定上传到的 Group，当某个 Group 的访问压力较大时，可以在该组增加 Storage Server 来扩充服务能力。
三、docker-compose文件
version: '3.3'
services:
tracker: # 调度器
image: season/fastdfs:1.2
container_name: fastdfs-tracker
network_mode: host
restart: always
command: "tracker"
storage: # 存储器
image: season/fastdfs:1.2
container_name: fastdfs-storage
network_mode: host
restart: always
volumes:
- "/fastDFS/storage/storage.conf:/fdfs_conf/storage.conf" # 存储器配置文件
- "/fastDFS/storage/storage_base_path:/fastdfs/storage/data" # 文件存储位置
- "/fastDFS/storage/store_path0:/fastdfs/store_path" # 存储配置
environment:
TRACKER_SERVER: "调度器ip和端口"
command: "storage"
nginx: # 客户端
image: season/fastdfs:1.2
container_name: fastdfs-nginx
restart: always
network_mode: host
volumes:
- "/fastDFS/nginx.conf:/etc/nginx/conf/nginx.conf"
- "/fastDFS/storage/store_path0:/fastdfs/store_path"
- "/fastDFS/pic:/hydf/fastDFS/pic"
environment:
TRACKER_SERVER: "调度器ip和端口"
command: "nginx"
四、客户端nginx配置

spring Boot集成
pom文件引入工具包
<!--fastDFS-->
<dependency>
<groupId>com.github.tobato</groupId>
<artifactId>fastdfs-client</artifactId>
<version>1.26.5</version>
</dependency>
java文件上传，这里因为名称长度有要求，所以我直接不要文件名字了，随机了一个然后加上原文件后缀
File file = new File(s);
String fileName = file.getName();
StorePath path = storageClient.uploadFile("group1", new FileInputStream(file), file.length(), fileName.substring(fileName.lastIndexOf(".") + 1));
System.out.println(path.getFullPath());
上传完成后的访问路径，由client所在的nginx客户端地址和返回回来的存储路径拼合就可以直接访问
http://{{nginx client客户端ip地址}}/group1/M00/00/00/CiQG-2ZeyV-AWmHcAA3vSx2O3n4972.png
